ACT-040, based on MEMS, is 3-axis accelerometer with very low noise. The sensor can real very high measurement repeatability. The principle includes an internal LDO to get stable accuracy voltage, which also reduces the sensor power supply. A 1.5kHz (50%) low pass filter is integrated to refine the signal output. The sensor includes wear-resisting cable with default length 8m. The LEMO connector and Dallas ID are optional.
